在本文中，我们提出了一种新的方法来提取单独填写的项目从日本银行支票的先验知识的基础上，他们的颜色特征和布局。我们已经分析了银行支票的特点，并提出了一个模型，可以用来提取填充项目适用于任何日本银行支票。首先通过模板提取填充项应该出现的区域。然后在HSV颜色空间中，根据填充字符和印章的颜色特征，提取出填充字符和印章。测试结果表明，该方法能够提取出日本银行支票中的填充项。
In this paper we propose a new method to extract separately filled-in items from Japanese bank-checks based on prior knowledge about their color characteristics and layout. We have analyzed the bank-check characteristics and proposed a model that can be used to extract the filled-in items applicable to any Japanese bank-checks. The areas where the filled-in item is supposed to appear are first extracted through a template. Then the filled-in characters and seal imprints are extracted on the basis of their color characteristics in HSV color space. The results of testing experiments show that this extraction method is capable of extracting the filled-in items from most Japanese bank-checks.
